8.8 cm Flak 18 New semi-automatic breech, high velocity gun. Entered production in Germany in 1933. Used the Sonderanhänger 201 trailer. Weight 7 tonnes. Rate of fire 15 to 20 rounds per minute. Later, fitted with a gun shield to protect the crew when engaging ground targets. Produced by Krupp. Mod 1938 II: Approximately 50 guns modified so a single man could adjust elevation and traverse.
8.8 cm Flak 36 Entered service 1936–37. It used the redesigned trailer Sonderanhänger 202 enabling faster time to action from the move. The SdAnh 202 had twin wheels on two similar carriages.

Produced by Krupp. Later, fitted with a shield to protect the crew when engaging ground targets. 8.8 cm KwK 36: Main gun of the PzKw VI Ausf. E (Tiger I) tank.
